Reactions of ketenimines with arene-sulfanyl and -selanyl chlorides: a general route to secondary amide derivatives and a new synthesis of C-sulfanyl- and C-selanyl-ketenimines
Abstract
Ketenimines 1, react with arene-sulfanyl and -selanyl chlorides to give the imidoyl chlorides 3 that either yield the substituted amides 4 upon solvolysis in aqueous acetone, or the C-sulfanyl- and C-selanyl-ketenimines 5 by dehydrochlorination with triethylamine.
